RAIL-ATTACHING MEANS.

Specification of Letters I atent.

Patented Oct. 3, 1916.

Application filed April 7, 1915. Serial No. 19,681.

' the cross-ties whereby they may be conveniently removed from the cross-tie and moved out of engagement with the rails.

A further object of the invention is to provide means of the above mentioned character, which are simple in construction, inexpensive to manufacture, strong and durable.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a central vertical longitudinal sectional view through one end of a plastic cross-tie showing the rail attaching means in section, Fig. 2 is an enlarged plan view of one attaching plate, Fig. 3 is an edge elevation of the same, and, Fig. 4 is a horizontal sectional view taken on line 4-4 of Fig. 1.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral5 designates a plastic tie which may be formed of concrete or other cementitious material and which is preferably provided with transverse and longitudinal metallic reinforcing means 6 and 7, as shown. The cross-tie 5 is provided near each end with a recess receiving a vertical casing 8, the bottom of which is closed by a plate 9. The casing 8 has its top flush with the upper surface of the tie 5, and a compressible coil spring 10 I is arranged within the casing. This spring is preferably formed of spring steel of 11;

inches diameter and is 3% inches long. There are preferably 24 .coils in the spring and when a load of 24,400 pounds is applied thereto the spring will compress solid. The ends of the spring are cut horizontally, as

shown. Engaging with the top of the spring 10 is a cover-plate or cap 11, extending transversely of'the cross-tie5 and provided with depending ends 12, disposed upon the opposite sides of the cross-tie.

The numeral 13 designates a rail disposed upon the plate 11 and yieldingly supported by the spring 10.

The numeral 14 designates the attaching plates as a whole, each of which embodies a horizontal outer base 15, carrying an inwardly extending portion 16, slightly angularly inclined for engagement with the top,

of the rail base and provided at its end with a vertical extension or lip 17, to engage with the vertical web of the rail. Each horizontal base 15 is provided with an elongated or approximately elliptical opening 18 extending longitudinally thereof for receiving a vertical bolt 19, extending transversely through the tie and having its head 20 embedded in the bottom thereof and preferably flush with such bottom. The bolt 19 extends through the elongated opening 18 and permits the securing plate 14 being verti cally tilted, whereby its upper end will clear the head of the rail upon being removed from or placed in the holding position.

The numeral 21 designates a filler, adapted to fit within the outer portion of the opening 18, and engage with the bolt 19, the same serving to prevent the attaching plate from slipping with relation to the bolt. This filler is held in place by a washer 22, having an eccentric opening '23, receiving the bolt 19, said washer being in turn held in place by a nut 24, having screw-threaded engagement with the bolt. It is thus obvious that the bolts 19 are permanently secured to or embedded within the cross-tie 5 and when it is desired to remove the attaching plates 14, the nuts 24 are unscrewed from their bolts. The fillers 21 are next removed, subsequently to which the plates 14 may be swung upwardly to clear the head of the rail 13 and subsequently wholly removed from the bolts: The reverse of this operation occurs when the plates 14 are being screwed to the'bolts.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention, I

5 claim 10 upper surface of the tie for a substantial distance, rail attaching plates disposed upon the upper surface of the tie and provided with horizontal extensions having elongated openings receiving the upper ends of the )5 bolts in the inner ends thereof, fillers 'dis posed Within the outer portions of the elongated openings to contact with the bolts, Washers carried by the upper ends of the bolts and having eccentric openings-receiving the bolts so that the washers completely span the elongated openings, and nuts having screw-threaded engagement with the up per ends of the bolts to engage the washers, substantially as described.

In testimony whereof I aflix my signature in presence of two Witnesses.
